Replying to Where to go

So I'm thinking about going on a trip out west either this coming season or the one after.  3 years ago I did a trip to Vail, Beaver Creek and Copper, which was pretty fun, but back then i wasn't into powder and natural terrain ie trees, open faces, cliffs, etc, and I've heard CO isn't the best that the west has to offer.  I'm just trying to figure out what region, like tahoe, pnw, rockies, BC, AK, southwest, etc of the west would make for a fun trip.  Specific states and even ski resorts are good too.  Basically I'm looking for a change from skiing the east and to have a fun time.  Mellow pow runs, pillow lines, trees, and small cliffs to drop sound fun.  Reliable snow is a must cause i want to hit some pow.   + Karma for anyone who helps.
